1. It can kill insects

Spraying the plant with milk can kill insects. Because the milk will solidify on the leaves and form a layer of mucous membrane. Smaller pests such as red spiders and aphids will be stuck by this layer of mucous membrane. After the milk is completely solidified, wash it in the running water to wash down the pests

2. Specific method

First prepare a box of milk and then pour it into the watering can. Then spray it where there are pests on the leaves. Note that the front and back of the leaves should be sprayed. If only the front is sprayed, the pests on the back may remain on the leaves

After spraying the milk, put the plant in a cool and ventilated place and wait for a few hours so that the milk on its leaves can solidify. Finally, put the plant under the running water to wash away all the small insects on the leaves
